CASTER-RETAINER.

Specification of Letters Patent.

Patented Oct. 31, 1905.

I Appliaation filed December 31, 1904. Serial No. 239,191.

caster-retainers, and has for its object to provide a holder that willserve the double purpose of yieldingly retaining itself and the casteragainst displacement while in use and at the same time to provide asimple, inexpensive, and durable retainer.

1n the accompanymg drawlngs, Flgure 1 1s a side elevation of my improvedretainer with a caster in place. Fig. 2 is a front elevation of myimproved retainer and caster, showing the base-plate and washer. cut incross-section. Fig. 3 is a partial perspective view of the frame of myimproved retainer, the top plate left off. Fig. 4: is a face view of thetop plate of the frame before it is bent into proper shape.

My invention is described as follows: The frame 1 of my improvedretainer consists of a wire 2, bent to form the bottom horizontal parts3, top cross parts 4, and vertical side parts 5 and 5. The retainer isconstructed of wire and holding-plates, the wire having considerableresiliency, such resiliency as to hold the retainer in place after thesame has been inserted in the leg of any kind of furniture or otherarticles where casters are desired.

Secured to the top cross parts 4: of the wire 2 is a top plate 6, thetwo ends 7 of which are turned downwardly and inwardly for looselyholding the upper cross parts 4. This top part 6 is also provided with acentral perforation 6. The ends 7 of the said top plate 6 are so formedas to allow said cross parts 4 to be sprung inwardly. The distancebetween the upper ends of the vertical parts of the wire from one viewis greater than the lower ends of said wire; but the distance betweenthe upper ends of the vertical wires from another view is less than thelower ends of said wire. These two features are clearly shown in theperspective view, Fig. 3.

The bottom horizontal parts 3 are secured in two projections 8, whichrise upwardly and inwardly from the face of a base-plate 9, having acentral perforation 10. These two projections 8 of the base-plate 9prevent the wire 2 of my improved retainer from slipping upwardly oroutwardly. Thus we have a retainer with a double spring adapted to besprung inwardly at its upper and lower parts, as desired.

The base-plate 9 has extending downwardly from its periphery a flange10. Working immediately under the base-plate and against the lower edgeof the flange thereof is a dished washer 11, the convex side of which isturned up. This washer has a central perforation, in which a pintle 12is mounted. This pintle 12 is provided at its lower end with a bulb 13or a flat shoulder, as may seem best, the upper part of said bulbresting and revolving against the lower face of the washer 11. Thepintle is also riveted Where it projects through the plate 6 to secureall parts of the retainer.

Secured to the lower end of the pintle and against the lower end of thebulb or flat shoulder is a bifurcated horn 15, between which thecaster-wheel 16 is journaled.

When my improved retainer is set in place in the usual opening in thebedstead or other leg, the resilient vertical sides 5 and 5 of the wire2 will bear upon the wall of said opening and retain the retaineragainst displacement. I

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. A caster-retainer, consisting of a baseplate 9, having in its centera perforation 10, and rising from its upper face, and near itsperiphery, projections 8, adapted to clamp a wire; a wire 2, bent so asto represent eight parts; two lower horizontal parts 3, two upper crossparts 4, two substantially vertical parts 5, and two substantiallyvertical parts 5, its lower horizontal parts 3, secured under theprojections 8, and a top plate 6, having a central perforation 6', andtwo downwardly and inwardly turned ends 7 the upper cross parts 4L, ofsaid wire, secured in said downwardly and inwardly turned ends, saidprojections 3, and ends 7, clasping said parts of said wire so as toallow them to spring inwardly, the substantially vertical parts of saidwire being wider in one view at their top ends than at their bottomends, and in another view wider at their bottom ends than at their topends, thus allowing said wire to spring inwardly at the top as well asat the bottom,

substantially as shown and described and for the purposes set forth.

2. A caster-retainer, consisting of a baseplate 9, having in its centera perforation 10, and rising from its upper face, and near itsperiphery, projections 8, adapted to clamp a wire; a wire 2, bent so asto represent eight parts, two lower horizontal parts 3, two upper crossparts 4:, four substantially vertical side parts 5, and 5, its lowerhorizontal parts 3, secured under the projections 8; a top plate 6,having a central perforation 6, and two downwardly and inwardly turnedends 7, the upper cross-pieces 4c, of said wire,- secured in saiddownwardly and inwardly turned ends, said projections 3, and ends 7,clasping said parts of wire so as to allow-them to springinwardly, thesubstantially vertical side parts of said wire being wider in one viewat their top ends than at their bottom ends, and in another view widerat their bottom ends than at their top ends, thus allowing said wire tospring inwardly at the top as well as at the bottom, forming a doublespring, and a perforated dished washer 11, working under and against theflange 10, of the base-plate 9, and
